In order to ensure that the APCUPS power supply can continue to provide high-quality power to the computer in the event of a power outage, it is particularly important to equip the battery backup battery. When the frequency load does not agree to be powered, the UPS battery backup time in the communication room should be greater than the time from the mains power suspension to rehabilitation or the time required for the normal power supply of the generator set (the front power supply system is equipped with a generator set), if this period is longer, it should be equipped with an external long-delay battery pack, but at this moment it should be confirmed that the UPS internal rectifier has the ability to charge the external large-capacity battery pack, then an external charger should be equipped.
The following guidelines should be followed for battery capacity selection:
The battery must be supplied to the inverter during the backup time, and the battery pack voltage should not drop below the minimum voltage promised by the inverter at rated load.
When placing the equipment in the computer room, the battery pack should be as close to the APCUPS host as possible, shorten the length of the connection between the two, and increase the cross-sectional area of the connection, so as to reduce the self-inductance of the connection and the voltage drop of the line.
The battery pack can be installed in the battery cabinet or in an open battery rack, the former is beautiful.
It is neat and tidy, but it has higher requirements for the bearing of the floor slab, the latter can disperse the load-bearing, and the heat dissipation is good, but it covers a large area, is easy to accumulate dust, and brings inconvenience to maintenance.

How Schneider UPS properly configures the backup battery
In order to ensure that the APCUPS power supply can continue to supply high-quality power to the computer even in the event of a power outage, it is important to equip the battery backup battery. When the load is not allowed to be powered, the UPS battery backup time in the communication room should be greater than the time from the mains power interruption to the rehabilitation or to the generator set is positive.

The role of Schneider thermal relays
The effect of the thermal relay is mainly used to carry out overload maintenance on the asynchronous motor, his operating principle is that after the overload current passes through the thermal element, the bimetal sheet is heated and bent to advance the action mechanism to drive the contact action, so as to disconnect the motor control circuit to complete the motor power-off thermal relay ...
